From 94de2291e005f1c646fd779e8d32b2820e22e071 Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Fri, 31 Jul 2020 16:54:31 -0700 Subject: *: initial implementation of pig This is nothing to write home about, but it provides a little sandbox for developing shader-generated textures in the spirit of shadertoy or the demoscene tool bonzomatic. It's more oriented towards developing shaders for use with libstage in the small games I've been hacking on. --- src/macros.h | 57 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 src/macros.h (limited to 'src/macros.h') diff --git a/src/macros.h b/src/macros.h new file mode 100644 index 0000000..091af77 --- /dev/null +++ b/src/macros.h @@ -0,0 +1,57 @@ +/* + * Copyright (C) 2018-2020 - Vito Caputo - + * + * This program is free software: you can redistribute it and/or modify it + * under the terms of the GNU General Public License version 3 as published + * by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
